It is unlikely that you would be able to see any change in the appearance of the string (I'm sure you would have reported it if you did). As you know, Monogut ZX is a very smooth string. Also, Zyex has a higher friction coefficient than poly, which makes it more susceptable to nicks and scrapes - one of the reasons for the detailed strining instructions we provide. I am wondering if this susceptability to friction is affecting the surface as you play and changing your ability to control spin. Of course, it could be something completely different.
Do you have access to a microscope or magnifing glass? If you do, I would recommend looking at the string from your hitting zone magnified and compare to the same magnification of unused Monogut ZX or some from the outer areas of the racket where your don't make much contact. Just an idea.
Julian, What are the recommended stringing instruction for Monogut ZX Pro?
I wait at least 5 seconds before clamping the string? Someone suggested longer. Also What is the recomended tension? It's stated that MGZXP should be strung 5-10% lower than normal, similar to what poly is recomended to be strung at.
